Abstract
Binder-free Cu-doped SnS 2 @CC electrodes with vertical grown nanosheet arrays are proposed. The highest capacity of 1092.8 mA h g −1 was got at 0.1 A g −1 , indicating that doping Cu can improve rate performance of SnS 2 , but excess Cu doping leads to reduced rate performance with overloaded defects.
